Electronic device

Abstract

In an electronic apparatus such as a wristwatch of the related art, in a case where a decorative member is simply disposed on a front surface side of a bezel, an impact from the front surface is directly transmitted from the decorative member to the bezel, and the impact cannot be suitably absorbed. An object of the present invention is to suitably absorb an impact.SOLUTION: A timepiece includes a bezel 22, and a decorative member including a cover part 44 arranged on the front side of the bezel with a gap S interposed between the decorative member and the bezel. Since the cover portion is configured to be deformable, when an impact is received from the front side, the impact applied to the cover portion is not immediately transmitted to the bezel, and the cover portion comes into contact with the bezel after being deformed.SELECTED DRAWING: Figure 6

DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of an electronic device according to the present invention will be described with reference to FIGS. It should be noted that the embodiments described below are subject to various limitations that are technically preferable for carrying out the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

[0009] 1(a) and 1(b) are a front view and a side view of a timepiece 100 according to this embodiment, and FIG. 2 is a cross-sectional view of the timepiece 100 taken along line AA in FIG. In the following explanation, the X, Y, and Z directions refer to the directions shown in the drawings. That is, the X direction refers to the 3 o'clock to 9 o'clock direction in an analog clock, the Y direction refers to the 12 o'clock to 6 o'clock direction, and the Z direction refers to the front-to-back direction of the clock 100 (clock body 2).

[0010] 1 and 2, a timepiece 100 according to this embodiment is an example of an electronic device according to the present invention, and is a wristwatch worn on the user's wrist. The timepiece 100 includes a timepiece body 2. The watch main body 2 is an example of a device main body according to the present invention, and has a cylindrical main body case 21. A bezel 22 is attached to the front side (viewing side) of the main body case 21. Bezel 22 is a first exterior member according to the present invention, and is formed in a substantially circular plate shape when viewed from the front, with a transparent windshield member 23 fitted inside. Bezel 22 in this embodiment is made of stainless steel, although this is not a particular limitation. The opening on the rear side of the main body case 21 is closed by a back cover 24 . In the following description, the "radial direction" refers to the direction perpendicular to the central axis Ax of the watch body 2 along the Z direction, and the "circumferential direction" refers to the rotational direction around the central axis Ax. Furthermore, the "inner diameter side" and "outer diameter side" refer to the inside and outside of the radial direction.

[0011] A clock module 25 is housed inside the clock body 2. A time display unit 25a that displays the time is located at the frontmost side of the clock module 25. If the time display unit 25a is analog, it includes a dial and multiple hands that rotate around the center on the dial to display the time. The time display unit 25a is visible from the front side through the crystal member 23. The clock module 25 also houses a battery as a power source, a circuit board on which a control circuit is mounted, a hand movement mechanism for moving a plurality of hands, and the like.

[0012] 3 and 4 are a perspective view and an exploded perspective view of the timepiece 100. FIG. As shown in these figures, the watch 100 has band attachment sections 30, to which bands 3 are attached, on both sides in the Y direction of the watch main body 2. The band attachment sections 30 connect the watch main body 2 and the band 3, and the connection section is covered with a decorative member 4 and a tip cover 5. The band 3 is formed in an elongated shape that extends within the YZ plane, and one end of it is connected to the watch main body 2. The band 3 is made of a soft synthetic resin such as urethane resin, and is flexible.

[0013] In the band attachment part 30, two bearing parts 21a are protruding from the outer surface of the main body case 21 on both sides in the Y direction, and are arranged side by side in the X direction. Meanwhile, three bearing parts 31 are protruding from the base end part (the end part on the watch main body 2 side) of the band 3, and are arranged side by side in the X direction. The watch main body 2 and the band 3 are connected (fixed) to each other by two screws 61 that penetrate them in the X direction, with the two bearing parts 21a of the main body case 21 and the three bearing parts 31 of the band 3 arranged alternately in the X direction and covered on both sides in the X direction by both side walls 51 of the tip cover 5. The band 3 is fixed to the watch main body 2 with its longitudinal direction roughly aligned in the Z direction. The two screws 61 are fastened with a fastening force strong enough to withstand the bending rigidity of the band 3.

[0014] Additionally, a front button 26 is disposed on the band attachment portion 30 on the 6 o'clock side. Front button 26 is positioned so that it faces diagonally forward in the 6 o'clock direction, and is supported by watch body 2 (main body case 21) so that it can be pressed in this diagonal direction. The tip of the shaft (not shown) of front button 26 is connected to watch module 25, and is configured so that pressing it causes watch 100 to perform a predetermined operation. Additionally, the periphery of front button 26 is protected by decorative member 4. Decorative member 4 has hole 41 at a position corresponding to front button 26, and covers the periphery of front button 26 while exposing it to the front side through hole 41. In this way, decorative member 4 protects front button 26 while guiding the movement of front button 26 in the pressing direction.

[0015] Furthermore, in the band attachment section 30, the connecting section between the watch body section 2 and the band 3 is covered with the decorative member 4 and the tip cover 5, as described above. The tip cover 5 covers the rear side of the connection between the watch body 2 and the band 3. The tip cover 5 restricts the band 3 from rotating rearward relative to the watch body 2.

[0016] The decorative member 4 is the second exterior member according to the present invention, and covers the connection between the watch body 2 and the band 3 from the front side (visible side). The decorative member 4 of this embodiment is made of epoxy resin containing carbon fiber, and is flexible yet relatively rigid. Specifically, the decorative member 4 has a member main body 42 and two protruding portions 43. The member main body 42 is the part that covers the connection between the watch main body 2 and the band 3. More specifically, the member main body 42 covers the connection between the watch main body 2 and the band 3 with almost no gap between the member main body 42 and the band 3 when viewed from the outside (visible side). The two protrusions 43 are provided on both sides of the component body 42 in the X direction and on the inside in the Y direction (inside the watch body 2). Each of the two protrusions 43 has a through hole 43a, and screws 62 inserted into the through holes 43a are fastened to the main case 21, thereby fixing the decorative component 4 to the watch body 2.

[0017] FIG. 5 is a perspective view of the decorative member 4 (on the 12 o'clock side) seen from diagonally below, and FIG. 6 is an enlarged view of part B in FIG. As shown in these figures, each protrusion 43 has a cover portion 44 arranged closer to the front than the bezel 22, and a fixing portion 47 that supports one side (outer diameter side) of the cover portion 44 along a direction (front direction) approximately perpendicular to the extension direction of the cover portion 44. The cover portion 44 is the most front side (upper side) of the protrusion 43, extends along the radial direction, and is arranged so that its tip faces the inner diameter side. The cover part 44 has an upper surface 45 with a vertex 45a located closest to the front, and a lower surface 46 with a bent portion 46a bent in a radially concave shape. The upper surface 45 is formed in a shape that slopes upward toward the inner diameter side, with the vertex 45a near its innermost diameter part. The lower surface 46 has an outer diameter side portion that slopes upward toward the inner diameter side, and an inner diameter side portion that is more inward than that and is substantially flat, with the bent portion 46a being the boundary between these outer diameter side portion and inner diameter side portion. The apex 45a of the upper surface 45 is located radially inward of the bent portion 46a of the lower surface 46, and in this embodiment, the apex 45a and the bent portion 46a are spaced apart by a distance L in the radial direction.

[0018] A gap S is interposed between the cover portion 44 and the bezel 22. This gap S is provided at least below the tip of the cover portion 44, and is formed so as to gradually widen toward the inner diameter side. Specifically, the upper surface of the bezel 22, which faces the lower surface 46 of the cover portion 44, has a tapered surface 22a that slopes downward toward the inner diameter side. This tapered surface 22a faces the flat inner diameter side portion of the lower surface 46 of the cover portion 44. Therefore, the gap S between the cover portion 44 and the bezel 22 gradually widens toward the inner diameter side (the tip side of the cover portion 44). However, there are no particular limitations on the specific shape, etc., of the gap S as long as it is interposed between the cover portion 44 and the bezel 22. For example, the upper surface of the bezel 22 may be a flat surface, and the lower surface of the cover portion 44 may be an inclined surface that slopes upward toward the inner diameter side. Furthermore, as long as the cover portion 44 is configured to be deformable, there are no particular limitations on the shape, material, etc. For example, the cover portion 44 may be supported (fixed) at a portion other than the outer diameter side (fixing portion 47), may not be made of a material that is flexible, and the extending direction is not limited to that of the present embodiment.

[0019] When a watch 100 having the above configuration is dropped or otherwise subjected to an impact from the front side, the vertex 45a of the cover part 44 of the decorative member 4, which is located closest to the front side, will first come into contact with the object of contact and receive the impact. At this time, because a gap S is present between the cover portion 44 of the decorative member 4 and the bezel 22, the impact applied to the decorative member 4 is not immediately transmitted to the bezel 22, and the cover portion 44 deforms downward before coming into contact with the bezel 22. Therefore, the impact can be suitably absorbed by the cover portion 44.

[0020] At this time, the cover portion 44 deforms such that the tip side bends downward, starting from the bent portion 46a of the lower surface 46. In other words, the deformation length is the radial distance L between the vertex 45a of the upper surface 45 and the bent portion 46a of the lower surface 46. Therefore, by appropriately setting the distance L, a suitable amount of shock absorption can be obtained. However, if the distance L is too short, the amount of shock absorption due to deformation will be reduced, whereas if the distance L is too long, the amount of deformation will be so large that there is a risk of cracking the cover portion 44. Therefore, it is preferable that the distance L be set to an appropriate length so that a suitable amount of shock absorption is obtained while reducing the risk of cracking due to deformation.

[0021] As described above, according to this embodiment, a gap S is interposed between the bezel 22 and the cover portion 44 of the decorative member 4, which is arranged closer to the front than the bezel 22, and the cover portion 44 is configured to be deformable. Therefore, when an impact is received from the front side, the impact applied to the cover portion 44 is not immediately transmitted to the bezel 22, but the cover portion 44 deforms before coming into contact with the bezel 22. Therefore, the impact can be absorbed suitably.

[0022] Furthermore, according to this embodiment, the cover portion 44 has an upper surface 45 having a vertex portion 45a located closest to the front, and a lower surface 46 having a bent portion 46a that is bent radially concavely, and the vertex portion 45a is positioned closer to the tip of the cover portion 44 than the bent portion 46a. Therefore, an impact from the front side first acts on the vertex 45a, and this impact causes the cover portion 44 to deform from the bent portion 46a as the deformation starting point. Therefore, the deformation mode of the cover portion 44 can be controlled, and therefore the amount of impact absorption can be controlled.

[0023] Furthermore, according to this embodiment, the gap S between the cover portion 44 of the decorative member 4 and the bezel 22 is formed so as to gradually widen toward the tip end of the cover portion 44 in the radial direction. This allows the cover portion 44 to be deformed appropriately when an impact is received from the front side, and therefore the impact can be absorbed appropriately.

[0024] It goes without saying that the embodiments to which the present invention can be applied are not limited to the above-described embodiments, and various modifications are possible without departing from the gist of the present invention.

[0025] For example, in the above embodiment, the decorative member 4 is made of epoxy resin containing carbon fiber, but there are no particular limitations on the material of the decorative member 4. However, it is preferable that the decorative member 4 is flexible and has relatively high rigidity.

[0026] Furthermore, in the above embodiment, the time display unit is an analog type, but it may be a digital type, or two time display units, one analog type and one digital type, may be provided.

[0027] In the above embodiment, the electronic device according to the present invention is described as being applied to a timepiece (wristwatch). However, the electronic device according to the present invention is not limited to timepieces and can be widely applied to devices that include two overlapping exterior members.
